How to use this auto loan calculator
Enter the negotiated vehicle price rather than the sticker price when possible. Add estimated sales tax, subtract your down payment and trade-in value, then use the APR and term offered by your lender. The result shows the estimated payment, total interest, and total of scheduled loan payments.
What the estimate includes
The calculator first estimates the amount financed, then applies a standard fixed-rate amortization formula. It does not automatically include title fees, registration, dealer products, insurance, late charges, or a trade-in loan balance.
Why APR and term matter
A longer term can make the monthly payment look easier while keeping you in debt longer and increasing interest. Compare 48-, 60-, and 72-month scenarios using the same price and down payment. Also request a preapproval so you can compare the dealer's financing with an outside offer.
Before signing a vehicle loan
- Confirm the out-the-door price in writing.
- Check whether the APR is fixed for the entire term.
- Review the amount financed and total of payments.
- Ask whether there is a prepayment penalty.
- Remove optional products you did not request.
Car Loan Calculator FAQs
Does this calculator include sales tax?
Yes. Enter your estimated sales-tax percentage. Registration, title, documentation fees, optional products, and insurance are not automatically included.
Is APR the same as the interest rate?
APR is the standardized annual cost of borrowing and may reflect certain finance charges. Compare lender disclosures using the same amount and term.
Why does a longer loan cost more?
A longer term spreads payments across more months but usually keeps the balance outstanding longer, which can increase total interest.
Can I use this result as a lender quote?
No. It is an educational estimate. Only a lender can provide an approved APR, payment schedule, and final loan disclosures.
